Los Angeles Chargers linebacker Joey Bosa addressed his fourth-quarter explosion that resulted in his second unsportsmanlike conduct penalty of the game and ultimately shifted momentum in favor of the Jacksonville Jaguars, saying Sunday he likely expects a fine from the league. 

Late in the fourth quarter after the Jaguars’ fourth touchdown of the game on Saturday, Bosa seemingly reacted to what he believed was a missed false start penalty.

As he approached the sidelines, Bosa launched his helmet into the ground before doing it a second time after Chargers head coach Brandon Staley handed it back to him.

The resulting unsportsmanlike penalty gave way to Jacksonville scoring a two-point conversion and narrowing the score to 30-28. 

Bosa declined to talk specifics of the helmet fiasco on Sunday, according to the NFL Network, adding that he expects some fines for the outburst.

"I do really, really want to say some things. I need to be more accountable for my actions, obviously, but it's a heated game and I'm hurting out there, I'm playing on half a leg, I'm getting dragged to the ground, whatever, could hurt me along with screwing our team, and yeah, maybe some of 'em weren't as blatant as I thought, but I don't know. I think there just needs to be more accountability," Bosa said via ESPN.

"I mean, if I say something to them I get a $40,000 fine but if they blow a call that ruins an entire team's season they get to -- they'll probably be back in the locker room after the game like, ‘Haha, got that a--hole, oh yeah, got him 15 yards, what a loser.’

"I guarantee it, that's what they're f---ing talking like in the back. Whatever power trip. I'm sick of those f---ing people."

Staley addressed Bosa’s frustrations throughout the game in his postgame presser. 

"I think he felt like there was a bunch of things that accumulated throughout the game and tried to talk through it with the officials. But we can’t lose our composure like that. We need to make sure that we stay on the high sides and we can’t hurt the team that way."
